HEAT EQUIPMENT.

Application filed May To all whom it maycomern:

Be it known that LOLrvni-i S. BOWMAN, a citizen of the United States, and a resident of Colorado Springs g in the county of El Paso and State of Colorado. have invented a new land useful Heat Equipment, of

i which the following is a specification.

' wish it understood that various changes in the details of construction may be made within the scope of what is hereinafter claimed.

l igure 1 represents a sectional plan view of the invention taken onthe line A i-kin l? 2; Fig. 2, anclevation of a section on the line G-Gin Fig. 8; Fig. 8, a plan view of the invention, thecap Gbeing removed; and Fig. 4, an elevation of a cross section on the line B li inFig. 3. 4

Thenneans for heating water for the radiator system consists of a primary waterheating chamber, comprising an annular lower section 1, a cylindricalintermediate section 2 and two segmental upper sections 3 and 4, with up-dratt tubes 5 and 5 through said cylindrical and segmental'sections; and a secondary water heating chamber (i enclosing said primarywater-heating chamber and having an inner insulating wall T and a segment 8 with down-drafttubcs 9 therethrough; said cylindrical intermediate section 2 having therethrough an insulated conduit 10 with damper 11 therein. Drain pipe 12opens above into segment 8 of the secondary water-heating chamber and below into intermediateseetion 2 of the primary water-heating chamber. 13 is a pipe connecting upper segmental sectionsil and 1 of theprimary waterheating chamber to the radiator s'yste1n,1and 1 1 isthe return pipefrom the radiator system and enters segmental section 8 of" secondary water-heating chamber 6.

Combustion chamber 15, hat-lug a tire door 16 and containing ire pot 17, is enclosedby the annular section 1 of the primary water-heating chamber and is in com smoke chamber 21.

munication with up-draft tubes 5 and and with insulated condult 10 having clamper 11 therein.

The two upper side smoke channels 18 and 19 communicate with the upper ends of tubes 5 and 5"; a rear upper smoke channel 20 communicates with the upper ends ot down-draft tubes 9; a central smoke Cl12111- nel '21 is in open communication with smoke channel 20 and in damper-controlled communication With side smoke channels 18 and 19 havmg therein dampers 18 and 19. A

lower smoke chamber 22 communicates with the 'lowerends of down-draft tubes 9. Smoke conduit 23 in com'municatlon with smoke channel 20 and smoke conduit 2a in communication with smoke chamber 22, are adapted tocommunicate with a chimney flue and are controlled by dampers 23" and 245 respectively.

The cooking means comprise chamber 25. having movable pa-rtition26, insulating wall 27 and doors %1, disposed above cylindrical section 2 and between segmental sections 3 and at and positioned to form a smoke channel, having sections 28, 29, and 30,111 communication below. with conduit 10 and above (via opening 81) with central Gas burners 32 and 32 and hinged batfle'33 are disposed in section 28 under cook ing chamber 25.

The means for heating water for domestic purposes comprise a series of connected pipes 34, having an inlet 35 controlled by valve 36, vertically disposed in rear segment 8, and a coil 37, having an outlet controlled by valve 38, horizontally disposed in central smoke channel 21and joined to said connected pipesfia by pipe 34.

The gases of combustion pass upward through tip-draft tubes 5 and 5" into smoke channels-18 and 19 thence through central smoke channel (assuming that both dampers 18 and 19 *are open and that damper 11 is closed) i'nto'rear smoke channel 20, down through-tubes 9 into lower smoke chamber 22'and through conduit 2% into the flue.

The hot water for heating'purposes flows from segmental sections 3 and 1, of the pri mary water-heating chamber, through pipe 13 into the radiator system, and returns therefrom through pipe 1d into the secondary water-heating chamber 6, where it is partly heated, as'it rises'therein, and flows through drain pipe 12 again into the intermediate section 2 of the primary waterheating chamber, where its reheating is completed.

The temperature prevailing in cooking chamber is regulated by the manipulation of dampers 11, 18 and 19. lVhen damper 11 is open and dampers 18 and 19 are closed, practically all the gases of combustion pass through conduit 10, smoke channel sections 28, 29, and and opening 31 into central smoke channel 21. The object of batlle is to retard the movement of the gases of combustion whilst passing under chamber 25.

If a direct draft is desired when starting a fire, damper 2st is closed and damper 23 opened.

\Vhen hot water heat is not required, gas burners 32 and 32 may be used to heat cooking chamber 25 and to heat water in coil 37.

lVater is heated for domestic purposes in pipes 3% and coil 37, pipe 35 being the inlet and valve 38 the outlet.

lVater is taken into the system through pipe 44; and may be drained from the primary water-heating chamber through pipe 42 and from the secondary water-heating chamber through pipe 43.

The removal of cap C permits access to tubes 5, 5 and 9.
